cartography

Aeronautical charts provide essential data for the pilot and air navigator. They are, in effect, small-scale topographic maps on which current information on aids to navigation have been superimposed. To facilitate rapid recognition and orientation, principal features of the land that would be visible from an aircraft in flight are shown to the exclusion of less important details.

navigational charts

Aeronautical charts are similar to nautical charts but emphasize such things as topography, heights of obstructions, airports, and airways. They are usually drawn on the Lambert conformal projection, which correctly preserves angles between different locations on the surface of the Earth.
